CALCULATING-MACHINE.

SPECIFICATION forming part of Letters Patent N 0. 712,518, dated November 4, 1902. Application filed September 26, 1901. Serial No. 76,680. (No model.) v

1'0 aZZ whom, it may concern:

Be it known that I, HYMAN ELI GOLDBERG, of the city of Chicago, county of Cook, and State of Illinois, have invented a new and usefulImprovementinCalculating-Machines, of which the following is a specification.

My invention relates to calculating-machines adapted for both adding and. subtracting; and the objects of my invention are, first, to construct a machine which shall be positive acting, avoiding the use of springs, ratchets, and other elements of uncertainty for preventing overthrow of the figurewheels; second, to provide a machine which shall be compact and consist of comparatively few parts of simple construction.

In order to illustrate the applicability of my invention to type-writing machines of known pattern, I have shown my calculatingmachine embodied in and attached to atypewriter; but my invention may with equal advantage exist as a. complete and independent machine, and, indeed, by disregarding the letter-keys and other parts superfluous to a calculating-machine the entire mechanism here shown becomes merely an adding and subtracting machine.

I attain these objects by the mechanism illustrated in the accompanyingdrawings,in which- Figure 1 is a front view of the machine attached to and operated by a type-writer. Fig. 2 is a plan view of the same, taken on the line 2 2,Fig. 1, and drawn to an increased scale. Fig. 3 is a vertical sectional view of the calculating-machine and type-writer looking in the direction of the arrows on the line 3 3, Fig. 1. Fig. 4 is a sectional view of the key attachment looking in the direction of the arrows on the line 4 4:, Fig. 3. Fig. 5 is a perspective view of the rack attached to the typo-writer carriage for operating the traveling gear. Fig. 6 is a top view of the traveling gear above mentioned.

Figs. 31 and 32 are diagrammaticviews showinganalternativemeth- 0d of driving the carrying-wheels-namely, by shifting the tenscarrying pinions laterally so as to mesh therewith one after the other, seriat'im. Figs. and 34 are also diagrammatic views showinganotheralternate method of driving the carrying-wheelsnamely, by

shifting the carrying-pinions as a single gang into mesh with the carrying-wheels. Fig. 35 is an assembly View looking in the direction of the arrows on the line 15 15, Fig. 11, illustrating the operation of the machine, particularly the fact that the cam is completely rotated in its setting-up action before the set-screw onthe key-rider comes in to contact with the arm for shifting the reversing mechanism.

Similar reference characters indicate similar parts throughout the several views.

In the present instance my calculating-machine is shown attached to a type-writer, known commercially as the No. 2 Remington, a (1 representing the standards of the main frame of the type-writer, b the top crossframe thereof, and c c the front extension or key-frame thereof.

dis the spacing-bar, supported on the spacing-bar arms 9 e, for permitting the carriage f to escape step by step toward the left. Said carriage fis supported in front by the roller g, traveling upon the top cross-frame b,while the rod h forms the support for the rear portion of said carriage.

The type-writer frame has a cross-pieced extending between the standards a a, and upon said cross-piece is secured the base-plate j of the caculating-machine. Said base-plate is provided with the posts k, which form the mountings for the cam-axle 'm. Said axle is conically pointed at its extremities,so as to fit into the correspondingly-recessed set-screws n a in said posts 70. In a similar manner the releasing-axleois mounted in the posts pp upon the under side of said base-plate j.

The cams q q consist of plates brazed or otherwise secured to the cam-axle m and having slots q therein which may, if desired, be open at one end, as shown. Each of said slots is preferably of uniform width throughout its operative length and receives a roller y, mounted in the key-riders, as hereinafter described. It is desirable that the slots g be so curved as to be tangent to the path of the rollers y at the final point in the downward travel thereof. By this construction the cams become temporarily locked in position and overt hrow or accidental rotation of the cam-axle is prevented. The cams are so constructed that the slots q extend beyond the extremepoints in the path of the rollers y, and therefore do not limit the travel of the said rollers and connected parts, thus avoiding any sudden shock or jar and preserving the resiliency of key action. As illustrated in Fig. 10, said cams are secured to the cam-axle m at different angles in order that said axle may be rotated definite amounts when acted upon by the respective keys,the quantity of rotation depending upon the face value of the key struck. Said cams are operated by key-riders which consist of plates 1 r, removably secured to the figurekeys 3 sof the type-writeriu the manner best shown in Fig. 4. The rider-block t is adapted to rest upon the shank of the key 3 and is brazed or otherwise secured to the plates 1*, so as to hold the same firmly together. The lower extremities of said plates 4* project below the key-shank, where they are provided with apertures u for receiving the wedgeblock '12. Said wedge-blocks, which are of a length somewhat greater than the distance between the outer faces of the rider-plates T, have double internal bevels so arranged as to engage said rider-plates at the apertures u therein. The set-screws 10, mounted in said wedge-blocks, are designed to bear against the sole-plates a; at the lower edge of the keys sin such a manner that when said screws are tightened the key-shank will be screwed in a vertical direction between the riderblock t and sole-plate 01:. At the same time the wedging action of the block U will cause the rider-plates r to be forced laterally toward said key-shank. By this construction the simple tightening of the screw w will cause the key-shank to be firmly engaged upon all four surfaces. When it is desired to remove the rider from the key, the setscrews are withdrawn from the wed ge-block i), when the parts may be readily disassembled. At their upper extremities said rider-plates carry therollers g which are adapted to act within the slots q of the cams q and rotate the axle m in the manner above mentioned. The rotation of said axle is imparted to the driving gear-wheel z by means of the link 1, which is pivotally connected at one extremity to said wheel and at the other extremity to the arm 2, said arm being brazed or otherwise secured to said axle m. The second driving-wheel 3 is secured to the said wheel a, so as to rotate therewith upon the arbor 4, projecting from the upright plate 5 of the machine-frame. Said wheels 2 and 3, operating as a single piece, tend to return to and remain in the starting position by the influence of the spring 6, which encircles the hub common to both of said wheels and is attached at one end to said hub and at the other end to a stationary part of the machine-for example,the pin 7. (Shown in Fig.

15.) Through the agency of the connectinglink 1 the returning of the wheels 2 and 3 to the initial position also returns the cam-axlem and cams thereon to their initial position. The return movement of the said driving gear-wheels and cam-axle is limited by said pin 7, which forms a stop for the arm 8, carried by the wheel .2.

Mounted so as to rotate freely upon the arbor 9, projecting from the frame-plate 5, are

the reversing-gear wheels 10 and 11, which are preferably integral with the hub or barrel 12. The inner wheel 10 is at all times in mesh with the drive-wheel 3, while the outer wheel 11 is at'a point out beyond the drivewheel a. The arbor 13, also projecting from the plate 5, is parallel to the. arbors 4 and 9 and carries the frame 14 for the master-pinion 15. Said frame is free to move lengthwise upon said arbor and is provided with a projecting hub 18, provided with the grooves 19 and 20, whereby said frame may be shifted upon the arbor 13, said groove 19 lying nearer the frame'plate 5. An automatic mechanism, which will be hereinafter described, is

provided for shifting the said hub and master pinion frame upon the setting axle 17;

p but it is sufficient for the present to say that the said frame may be caused to assume four distinct positions, the master-pinion 15 being, first, in mesh with the gear-wheel 11, as shown in Fig. 16; second, out of mesh with said wheel 11 and located between said wheel 11 and the wheel .2, as shown in Fig. 17,; third, in mesh with said wheel a, as in Fig. 18, and, fourth, out of mesh with said wheel ,2, as shown in Fig. 19.

The above-mentioned mechanism for shifting the frame l t is operated by the drivingwheel ,2; but it is necessary that said pinion shall not interfere with the wheels .2 or 11 while said pinion is being shifted back again into its original position. In order that the shifting motion of the pinion may be completed before the latter begins to rotate upon the new stroke, certain of the teeth of said wheels .2 and 11 are cut away. It will be apparent by referring to Fig. 15 that in the present instance said wheels 2 and 11 will rotate approximately three teeth before engaging said master-pinion, this amount of rotation being suflicient for the completion of the shifting act-ion of said wheel 2. In other words, it will be understood that when the driving-wheel z is about to start upon a newstroke the pinion 15 is in line to mesh therewith, and such meshing does take place when said drivingwheel has been rotated far enough for its teeth to engage the teeth of said pinion. YVhen the forward motion of the drivingwheel .2 has been completed, the pinion is shifted to the side out of mesh with said driving gear-wheel. Said pinion remains at the side of said driving-wheel out of mesh therewith until said driving-wheel has nearly completed its return stroke; but during the final part of the return stroke of said drivingwheel .2 said pinion is shifted back again into line with said driving-wheel, and it is to prevent interference during this last part of the return stroke of said driving-wheel that the first few teeth of said driving-wheel are cut away. As it is necessary that said pinion 15 shall not rotate previous to its engagement with the said wheels ,2 and 11, a safety locking device is provided,which consists of an arm 21, pivoted on the arbor 22, projecting from the frame-plate 5. Said arm is adapted to swing into and out of engagement with said pinion 15 and is operated by meansof the arm 23. Said arm 23 is inturn actuated by the lug 24,

formed upon the wheel 3, as shown in Fig. 14, and the parts are so timed that said detaining-arm 21 will release the pinion 15 just prior to the engagement of said pinion with the respective gear-wheels. A spring 25 tends to keep the arm 23 in its proper position. An-

other safety device consists of the fixed locking-bar 26. (Best shown in Figs; 15, 16, and 17 and diagrammatically in Fig. 17%) Said bar is secured to the frame-plate 5 and engages the pinion 15 when the latter is out of engagement with the locking-arm 21, Wheel 11, or wheel The notch 27 in said fixed bar permits said pinion 15 to rotate when the latter is in mesh with the driving-wheel The frame-plate 28, which in the present instance is similar to the frame-plate 5, is secured to the base-platej and forms a support for parts of the mechanism, as will hereinafter appear. The setting-axle 17, which carries the master-pinion 15, extends to and has a bearing in the said plate 28, and the setting-pinion 29 is splined to said axle, so as to rotate therewith and beushiftable thereon. The position of the pinion 29 lengthwise upon the axle 17 is controlled by the arms 30 30, which form a part of the slide bar or plate 31. Said slide-bar is supported in the plates 5 and 28 so as to be free to move longitudinallyand is provided with a toothed rack'32, which is engaged by the gear-wheel 33, whereby said slide-bar is shifted. The gear 33 is fastened to the spindle 34, which has a bearing on the base-plate j,.and also in the top cross-frame b. At the upper extremity of said spindle is the pinion 35, which is so located as to be engaged by the toothed rack 36, formed upon the depending portion of the carriage-plate 37. The parts are so related that when the carriage f, carrying said plate 37, has brought the rack 36 into mesh with the pinion 35 the step-by-step escaping motion of'said carriage will impart a corresponding motion to the slide-bar 31. .By referring to Fig. 1 it will be seen that the rack 36 is not in engagement with the pinion 35 at all positions of the carriage f, but that such engagement does not commence until the said carriage has reached a position near the left of the main frame of the machine. This means that the calculating mechanism is inoperativeuntil the carriage has brought the recording sheet of paper to such a position that the type will be printed near the right edge of the paper.

The purpose of this arrangementwill .be obvious when it is borne in mindthat it is the common. praotice in billing, invoicing, and tabulating to write the description of the items atthe left portion of the sheet and to write the numbers to be totalized in a column only during the printing of the numbers to be totalized. This provision whereby the calculating mechanism acts during a portion numbers to be totalized.

In order that the position of the column of figures upon the recording-sheet may be varied, the plate 37 is adjustably attached to i the carriage f, said plate having elongated slots 38 for receiving the set-screws 39. The apertures 40 in said plate are adapted to receive a pin (not shown) upon thecarriage for the purpose of accurately determining theproper locations for said plate.

It is desirable that the slide-bar 31 be accurately placed during the rotation of the setting-pinion 39, and to attain this an adjusting device is provided which consists of a detaining-arm 41, mounted in the lug 42 on the frame-plate 28, said arm being acted upon by the spring 43 in such a manner that a portion of said arm tends to enter the notches 44 in the slide-bar 31. The slides of said notches are beveled in order that said arm may easily force its way into and be forced out of engagement with said notches when the slidebar is moved by the toothedgearing.

The sliding locking-bar 31 extends along theedge of the slide-bar 31 in such a manner as to engage and lock the idler-wheels 60, hereinafter referred to. This locking-bar is formed on the slide-bar to the right of the pinion 29, so that it is only the idlers to the right of said pinion which are locked by said bar. As said slide-bar progresses toward the right said idlers will be releasedone after the other just prior to their coming into gear with said pinion 29. This prevents the rotation of the figure-wheels to the right of the one in geared connection with said pinion.

The slide-bar 31 has a slot 45 for receiving the pins 46 46, which are formed at the upper extremities of the rocking frames 47 47. Said slot consists of two straight portions which extend lengthwise of the bar, but which are oflset relatively to each other in such a manner as to form a cam for moving said pins 46 in a direction transverse to the length of the bar and for locking said pins at each extremity of their throw. Said frames 47 are pivoted upon the fixed bar 48 and have the ten carrying-pinions 49 revolubly mounted near their lower extremities.

Said frames are maintained in their proper positions on the bar 48 by the spacing-collars 50. (Best shown in Figs. 11 and 13.) Each of said pinions comprises three sections arranged side by side across the width of the pinionthat is to say,

of the sections 52 and 53.

in the direction of the axis thereof. Referring to Fig. 20, the section 51 at the left is a complete toothed gear having an even number of teeth,while sections 52 and 53 are mutilated by the removalof every alternate tooth.

By preference a gear is selected having eight teeth, thereby leaving four teeth upon each Said mutilated sections are so relatively placed that the remaining teeth alternate one with anotherthat is to say, are staggered-so that a tooth on one section is adjacent to a spacenpon the other.

The carrying-wheels 54 are mounted so as to rotate independently upon the fixed bar 55 and are also composed of three sections, the section 56 upon the right being a'complete toothed gear adapted to mesh with the section 51 of the pinions 49. This section 56 has some multiple of twenty teeth, the present wheel being provided with twenty. Sections 57 and 58 of the wheels 54 are disks each having circular peripheries, which are -d rawings. These overlapping portions maybe regarded as carrying-teeth, and although the preferred number upon each carrying-wheel is two an even number consisting of four or more such teeth may be employed. present machine shows two overlapping teeth to correspond to the section 56, which has two sets of ten teeth. In general the number of overlapping carrying-teeth must be the same as the number of sets of ten teeth on the section 56. I The wheel-sections 57 and 58 engage with and intermittently drive and lock the pinions 49. r

By reference to Figs. 26 and 27 it will be seen that pinions 49 are ordinarily locked by the carrying-wheels 54, except when the overlapping carrying-tooth reaches the pinion 49.

At this time the carrying-wheel rotates the pinion 49 one tooth and immediately locks it again. Since there is an overlapping tooth for each set of ten teeth upon wheel 54, this results in turning pinion 49 one tooth for every tenth tooth of wheel 54. The intermittent rotating and meantime locking of the pinions 49 by the wheels 54 results from the fact that when a tooth upon the pinion-section 53 is in juxtaposition to the root-circle portion of the disk 57 the point-circle portion of the disk 58 lies between two teeth of the pinion-section 52, as shown in Figs. 26 and 27.

Referring to Fig. 20, it will be noted that the pinions 49 are so located as to engage two different wheels 54, the mutilated sections 52 and 53 of any given pinion engaging the disks 58 and 57 of one wheel 54 and the complete section 51 on said given pinion engag-' ing the section 56 on the next higher wheel 54. Consequently whenever a wheel 54 turns the pinion 49 one tooth it also turns the next higher wheel 54 one tooth, thus carrying the tens. When the carrying-pinions 49 are swung out of mesh with the carrying-wheels The . consecutively.

-54 by the rocking frame 47, said pinions are locked by the fixed locking-bar 59. (Shown in Fig. 13.)

The idler-wheels 60, mounted so as to rotate independently on the fixed shaft 61, mesh with their respective carryingavheels 54 and also with the gears 62 on the figure-wheels The shafts 61 and settingaxle 17 are so relatively placed that the setting-pinion 25 will mesh with and drive said idlers when shifted to positions opposite thereto. Said figurewheels (shown separately in Fig. 28) are cylinders or barrels bearing on their peripheral surfaces the numeral characters 0 to 0, The fixed shaft 64, whereon said wheels are revolubly mounted, is so placed that said idlers mesh with said gears 62.

The mechanism for releasing and shifting the master-pinion 15 will now be described.

Upon the key-rider plates 4' are thelugs 65, which carry set-screws 66, adapted to engage the arms 67 67 on the releasing-axle o. Said arms are rigidly secured to said axle, and the depression of any keys results in the partial rotation of the said axle. The plate or segment 68, which is also rigidly secured to said axle 0, constitutes a cam for acting upon the roller 69, carried at the extremity of the releasing-lever 70. The rear portion of said cam-plate 68 is circular about the axle 0 as a center. Therefore when said roller 69 is on said circular portion said roller and the lever 70 are locked in position, while said cam-plate is free to move backward and forward. By this construction there is, practically speaking, no limit to the motion of said cam-plate and releasing-arms 67, and consequently the travel of the keys .9 is in no wise limited by said cam-plate and releasing-arms. Said lever is pivotally mounted on the arbor 71, so that the forward arm 72 of said lever will engage the bar 73, pivoted on the log 74. The approximately upright rod is rigidly secured to the said bar 73 and carries a lug or arm 76, which extends approximately horizontally from said rod 75 in a direction toward the driving gear-wheel z. The pin 77 is also secured to said rod. (Shown in Figs. 16, 17, 18, and 10.) The lateral or approximately-horizontal movement of the pin 77, due to the rotation of the arm 75 about its pivot, will effect a shifting of the frame 14: and master-pinion 15 mounted therein. The cam 68 is normally held by the spring 68 in such a position that the lever 72 is disengaged from the bar 73. It is only after the settingup action of the master-pinion 15 is completed on the downstroke of the keys that said cam throws the lever 73 and shifts the said pinion 15 out of mesh with its coacting gear-wheels or 11, but at the same time shifts it onto the bar 27, thus lockingit into position. The

lug 78 on the driving-gear is beveled in such a manner that when said lug is in engagement with the lug 76 the rotation of said drivinggear in a rearward direction toward the initial or starting position will throw said lug 76 in a direction away from said gear 2. This causes the master-pinion 15 to be shifted toward the gear-wheel 11. The amount of travel of the gear-wheel z necessary for the action of the lug 78 on the lug 76 is equivalent in the present machine to about three teeth of said gear, and it is for the purpose of permitting the completion of such action that the teeth on said gear-wheel z and also upon the gearwheel 11 are so cut away that said wheels will not operate upon the master-pinion 15 during the shifting action of said mastenwheel. The upright rod 75 is of such resiliency that the pin 76 may be temporarily withdrawn from the hub 18, so that the frame 14, carrying the master-pinion 15, may be shifted to bring either the slot 19 or the slot 20 opposite to said pin 77, depending upon whether it is required that the machine shall add or subtract. The parts are so arranged that when the pin 77 is in the slot 19 the action of the lug 78 will be to throw the said pinion into engagement with the gear-wheel 11, and when .said pin 77 is in the slot 20 the action of said lug 78 will be to throw said pinion 15 into engagement with the gear-wheel ,2. It will be noted, therefore, that the action of the cam 68 upon the master-pinion 15 is opposite to the effect of the lug 78 on said master-pinion. By the action of the cam 68'said pinion will be thrown out of engagement or released from the gear-wheels ll or .2, while the effect of the lug 78 is to throw said pinion into engagement with the said wheels 11 or .2. The parts are so timed that the pinion 15 will be laterally shifted into the plane of the wheel for meshing therewith just prior to the end of the return motion of said wheel .2 and will be laterally shifted out of said plane and will be locked after the setting-up action is completed at the end of the forward stroke of said wheel.

The operation of the machine is as follows: \Vhen used in connection with a type-writing machine, the slide-bar 31 is ordinarily at such a place that the setting pinion 29 is out of mesh with the idler-wheels 60, so that should a figure-key be struck when the type is being printed on the left portion of the recording-page said pinion will rotate without affecting the calculating mechanism; but should the pinion have been brought into mesh with some one of the wheels 60 then the rotation of said pinion would affect the mechanism, and this pinion is so brought into mesh whenever rack 36 passes pinion 35. From this it is evident that the mechanism operates for a definite column of figures and at no other place, and in that column it is affected by the highest figure first and the units last. Let it be supposed that the number 5678 is to be set up and printed, that all of the figure-wheels are at "'O, and that the machine is set for addition-that is to say, pin 77 is in the slot 20, as shown in Figs. 18 and 19. \Vhen the carriagefis in the proper position, the setting-pinion 29 will be opposite toand mesh with the fourth one of the idler-wheels 60,'and consequently will be in gear with the fourth one of the figure-wheels 63, counting from the right end of the gang.

All the ten carrying-pinions 49 to the left are now inmesh with their respective wheels 54, and all those to the right are out of mesh with wheels 54, but in mesh with the locking-bar 59, while all the wheels 60 to the right of the setting-pinion are firmly locked by the lock- .now. depressed, which causes the roller y,

mounted thereon, to throw the respective cam g and cause the proper amount of rotation of the cam-axle m, gear-wheels a and 3, and gear-wheels 10 and 11. The rotation of the wheel .2 is imparted to the master-pinion 15 and thence to the setting-pinion 29 through the medium of the splined axle 17.

Just prior to the mesh- 24 on the wheel 3 operates upon the arm 23 to release the detent 21 from said pinion. After this setting-up action is completed, but

before the completion of the downward stroke of the key, the set-screws 66 thereon strike an arm 67 and, acting through the releasingaxle 0, rotates the cam 68 so as to throw the lever 72 and bar 73 downward, thereby shifting theh ub 18 and'frame 14 and throwing the pinion 15 sidewise out of mesh with the gearwheel 2. As said pinion moves away from said wheel z it moves onto and is locked by the fixed bar 26. On the upward stroke of the figure-key the carriage f escapes one step.

toward the left, and the slide-bar 31 is thereby moved one' digital place to the right, consequently bringingthe setting-pinion 29 to a position to set up the third figure-wheel-that is, the wheel occupying the hundreds place or column.

upon the cam q, thus permitting the wheel .2 and cam q to be brought back to the original position by means of the spring 6. the end of the backward stroke of the wheel 2 the lug 78 operates upon the lug 76, thereby throwing the upright rod and frame 14 so that the master-pinion 15 is again brought opposite to the gear-wheel z preparatory to the next key-stroke. At the same time the lug 24 operates upon the lever 23 to lock pinion 15 by'means of lever 25 to prevent accidental rotating while out of mesh with the wheel 2'. The same operation is now repeated with the figure-keys bearing the characters 6, 7, and '8 in order, the setting-pinion 29 being each time shifted one place to the right. Suppose the number 234 is to be added to the This" causes the character 5 to be set up on the; v fourth figure-wheel.

ing of the wheel a with the pinion 15 the lug As the figure-key approaches the. end of the upward stroke it releases its hold Toward number 5678 alreadyset up and printed.

The carriage f is moved to such aposition that when the key bearing the character2 is struck said characterwill be printed in the hundreds place-that is, the third from the right or units column on the recording-sheet.

This placing of the carriage will so place the slide-bar 31 as to bring the setting-pinion 29 opposite the third figure-wheel, counting from the right of the set of said wheels. figure-key bearing the character 2 is struck, the hundreds figure-wheel will be rotated the space of two characters, and in a similar manner the tens-wheel willbe rotated three'spaces,

and the units-wheel four spaces in setting up said number 234. Said numbers now appear on the printed sheet in the following ar-, rangement: v v

but the efiect on the figure-Wheels is modified by the tens-carrying mechanism. The wheel in thousands place remains unchanged, but thehundredswheel has been rotated two spaces and is therefore set to f 8.. In being rotated three additional spaces the tens-wheel. which was already at 7, passes beyond 9 and shows 0, having made one complete revolution. Since the figure-wheelsare geared to the carrying-wheels 54, it follows that the When the respective carrying-wheel has been rotated ten spaces, thereby causing one carrying-tooth on the disks 57 and 58 to pass a carryin g-pinion 49 and drive the latter one space; but, as is shown in Fig. 20, each carrying-pinion is geared also to the next carrying-wheel to the left, and so the complete revolution of the tens figure-wheel is transmitted to the hun-- dreds figure-wheel at one-tenth of a complete revolution of the latter. In other Words, the

ICC

tens is carried to the hundreds wheel, and

therefore said hundreds-wheel is rotated so as to show 9 instead of the 8, as it did just prior to the carrying. Therefore the numberappearing on the figure-wheels before the addition of the final 4 of 234 is as follows: 5908, the units-wheel being as yet unchanged. The addition of the final 4,

'IIO

however, drives the units-pinion from ,8

to the twelfth space, which is two beyond the zero-point, and the units-wheel shows 2; but in having completed the revolution the units-wheel has caused the tens-wheel to be rotated one space from O to 1 through the agency of the carrying mechanism, as above described,and the total appears thus: 5912. Attention is directed to the fact that all the figure-wheels to the left of the one being temporarily acted upon by the settingpinion 29 is subject to the operation of the tens-carrying mechanism. In otherwords, the figure-wheels whose place values are higher than the place value of the figure-wheel temporarily in mesh with the setting-pinion are in gear, so that the tens may be carried as is common in counting mechanism. On account of of rotation of the wheels 2 and shifted .seriattim.

the construction of the tens-carrying wheels and tens-carrying pinions the parts of the present mechanism to the left of the settingpinion constitute simply a locked counting mechanism, whereas those to the right of said pinion constitute merely a locked series of loose disks.

The process of subtraction will now he described. As the figure-wheels 63 and the parts of the carrying mechanism are so constructed as to be reversible it is only necessary that after the minuend has been set up on the figure-wheels the eifeet of depressing a figure-key s will be to rotate the figurewheels backward in a direction opposite to the direction required in adding. This reverse action of the figure-keys is attained by shifting the master-pinion 15 so that it will be driven by the gear-wheel 11 instead of the gear-wheel .2 when the key is being depressed. This will be evident by referring to Figs. 16 to 19, for the gears 10 and 11 are employed merely as idle gears to reverse the direction Therefore when the machine is to subtract the pin 77 on the rod '75 is set so as to work in the slot 19 on the hub 18. This causes the masterpinion to mesh with the wheel 11 during the depression of the figure-keys and to be shifted to the sides of said gear, as shown in Fig. 17, during the upstroke of said keys. In order that the tens-carrying pinions 49 may be moved into mesh with the tenscarrying wheels serictt'im, commencing with the pinion corresponding to the highest place value in the number to be set up, the frames 457 are swu ng seriai'im by the slide-bar 31. This operation is illustrated diagrammatically in Figs. 29 and 30, wherein If) represents the pinions and the carrying-wheels. The same result may, however, be accomplished in different ways, two alternate methods being shown in Figs. 31 to In Figs. 31 and 32,49" represents carryingpinions, which are here mounted so as to he shiftable on the fixed bar 79. Each of said pinions may be shifted into mesh with its respective carrying-wheel 5i and would be so In this method each pinion will have only a slight travel, merely sufficient to accomplish the meshing and unmeshing.

Figs. 33 and 3t show a method in which the pinions Mi are independently rotatable upon the fixed shaft 79, but are shiftable on said shaft as a single gang. Said pinions approach from the left and progress toward the right.

The method of returning all the figurewheels to zero is to set up the machine to sub tract and then strike the figure-keys which represent the number set up onthe figurewheelsthat is to say, the figu rewheels may all be set to zero by subtracting the number shown thereon.

One of the features of my machine lies in the opportunity it affords for checking errors in recording footings or remainders. For example, suppose it is desired to record on the printed page a given number and at the same time set all the figure-wheels to zero. Now it the operator strikes thewrong figure-keys the figure-wheels will not show zero, but will show some number, and this will represent the amount of error existing between the number which the operator did print and the given number which should have been printed. Consequently the number appearing on the figure-wheels after said wheels were expected to come to zero represents the amount of error in recording, and since the amount of error is known correction may easily be made.
